Provide some quotes as evidence to prove that Simon is a static character in Lord of the Flies.

A static character, in literary terms, is one who undergoes little or no inner change. It is a character who does not grow or develop.

Simon is anything but a static character. He is actually the one who gains new insight and comes to understand our inner fears and innate barbarity. He is the character who concludes that we have nothing to fear but ourselves and it is this fear and our inbred savage nature that makes us turn against each other instead of resolving our inner conflict.

Simon draws attention from the outset. He is the boy that faints at the beginning and who, apparently, had been consistently doing so even during the boys' flight. In spite of the fact that he is small and frail, Ralph chooses him to accompany Jack and himself to further explore the island, instead of one of the bigger boys. He is the one who conscientiously helps Ralph in building the shelters and who supports his leadership telling Ralph that he is the leader and that he should tell the other boys off for not assisting.

It is also Simon who suggests that the beastie or snake thing was not real and mentioned that the littluns acted as if it were. Simon, of all the others, is the one who fearlessly goes deeper into the island where he finds himself in a secluded spot. It is here where he essentially becomes one with his surroundings, one with nature, as suggested in the following extract:

When he was secure in the middle he was in a little cabin screened off from the open space by a few leaves. He squatted down, parted the leaves and looked out into the clearing. Nothing moved but a pair of gaudy butterflies that danced round each other in the hot air. Holding his breath he cocked a critical ear at the sounds of the island.

We also see that Simon is, more than any of the other boys, prepared to share and help. He does this with the littluns when he helps them get fruit and he gives Piggy his share of the meat when Jack refuses to give him any. It is also Simon who recognises the inner beast in all of us but when he tries to share this insight with the others, they cannot understand.

“What I mean is. . . maybe it’s only us.”
“Nuts!”
That was from Piggy, shocked out of decorum. Simon went on. “We could be sort of. . . ”
Simon became inarticulate in his effort to express mankind’s essential illness. Inspiration came to him.
“What’s the dirtiest thing there is?”

The response was Jack uttering a crude, disgusting word which created uproarious laughter and Simon was forgotten. Simon's insight is constantly displayed such as:

However Simon thought of the beast, there rose before his inward sight the picture of a human at once heroic and sick.

Simon is the one who encounters the Lord of the Flies which is a pig's head on a stick and here realises the truth about their fear.

...in front of Simon, the Lord of the Flies hung on his stick and grinned. At last Simon gave up and looked back; saw the white teeth and dim eyes, the blood—and his gaze was held by that ancient, inescapable recognition. In Simon’s right temple, a pulse began to beat on the brain.

During this incident, Simon hallucinated and then fainted. He then ventured further up the mountain since he believed that that would be the only way to discover the truth about the beast and found the dead parachutist's body, surrounded by flies. He realised that that was what Sam and Eric had seen. He released the body from its trappings and decided to go down to the beach to inform the others of his discovery. This was to be his final act, one which he had foreseen during his hallucination.

When Simon reaches the beach, just as a storm came up, he cries out what he had seen. The other boys, thinking that he is their worst fear come to life, attack him in a frenzy. Ralph and Piggy join in and Simon is killed. His body is later washed out to sea. Simon had become a victim of the other boys' deepest and most profound fear.
